Animal Biochemistry
Introduction
Animal biochemistry is the study of the chemical composition and reactions occurring in animals. It is a branch of biochemistry that focuses on the biochemistry of animals, including humans.
Basic Concepts
- Metabolism: The sum of all chemical reactions that occur within a living organism.
- Enzymes: Proteins that catalyze chemical reactions in living organisms.
- Hormones: Signaling molecules that regulate various physiological processes in animals.
- Nutrients: Substances required by animals for growth and energy.
- Metabolites: Intermediate products of metabolism.
Equipment and Techniques
- Spectrophotometer: Used to measure the absorbance of light by a substance.
- Chromatography: A technique used to separate and analyze mixtures of substances.
- Electrophoresis: A technique used to separate charged molecules.
- Mass spectrometry: A technique used to identify and characterize compounds based on their mass-to-charge ratio.
- Microscopy: Used to observe and study cells and tissues.
Types of Experiments
Animal biochemistry experiments can be divided into two main types:
- In vitro experiments: Conducted using isolated cells or tissues in a controlled laboratory environment.
- In vivo experiments: Conducted using whole animals, allowing for the study of biochemical processes within a living organism.
Data Analysis
Data analysis in animal biochemistry involves the use of statistical methods to interpret experimental results.
- Descriptive statistics: Used to summarize and describe the data.
- Inferential statistics: Used to make inferences about the population from which the data was collected.
- Bioinformatics tools: Used to analyze large datasets and identify patterns.
Applications
Animal biochemistry has applications in various fields, including:
- Medicine: Diagnosis and treatment of diseases.
- Veterinary science: Animal health and welfare.
- Agriculture: Animal production and nutrition.
- Forensic science: Identification and analysis of animal tissues.
- Biotechnology: Development of new drugs and therapies.
Conclusion
Animal biochemistry is a dynamic and interdisciplinary field that provides insights into the chemical composition and reactions occurring in animals. By studying the biochemistry of animals, we can better understand health and disease processes, develop new therapies, and improve animal welfare.

Experiment: Determination of Creatinine in Urine
Significance
Creatinine is a by-product of muscle metabolism and is excreted in urine. Its concentration can provide valuable information about muscle mass and kidney function.
Materials
24-hour urine sample Creatinine standard solution (1 mg/dL)
Jaffé reagent Spectrophotometer
Procedure
1. Pipette 1 mL of urine into a test tube.
2. Add 1 mL of Jaffé reagent and mix thoroughly.
3. Incubate at 37°C for 10 minutes.
4. Measure the absorbance at 540 nm using a spectrophotometer.
5. Prepare a standard curve using known concentrations of creatinine standard solution.
6. Calculate the creatinine concentration in the urine sample using the standard curve.
Key Procedures
Urine Collection: Collect a 24-hour urine sample to obtain an accurate representation of creatinine excretion. Jaffé Reaction: The Jaffé reaction forms a colored complex with creatinine, allowing its quantification.
Incubation: Incubation at 37°C ensures optimal reaction conditions for the Jaffé reaction. Spectrophotometer Measurement: Absorbance at 540 nm corresponds to the amount of creatinine present in the sample.
* Standard Curve: A standard curve allows for accurate concentration determination by comparing absorbance values with known creatinine concentrations.
Expected Results
Normal creatinine levels in adults range from 0.5 to 1.5 mg/dL. Higher or lower levels may indicate muscle disorders or kidney disease.
