Malnutrition of proteins can lead to various diseases and health conditions due to insufficient intake or inadequate absorption of essential proteins. Protein malnutrition can manifest as both protein deficiency (kwashiorkor) and overall malnutrition (marasmus). Here are details on diseases related to protein malnutrition: 1. Kwashiorkor Cause: Kwashiorkor is primarily caused …

Qualitative tests and the biological role of proteins and amino acids
Qualitative Tests for Proteins Various qualitative tests are employed to identify the presence of proteins in a biological sample. Here are some common methods: 1. Biuret Test Principle: The biuret reagent reacts with peptide bonds, producing a violet color in the presence of proteins. Procedure: A sample is mixed with …
Protein Structure: Four Levels of Organization
The structure of proteins is organized at four distinct levels: primary, secondary, tertiary, and quaternary. Each level of the organization contributes to the overall shape, function, and stability of a protein. Here’s a detailed explanation of each level: 1. Primary Structure – Definition: The primary structure of a protein refers …
Amino Acids: Definition, Classification, and Nutritional Significance
Definition: Amino acids are organic compounds that serve as the building blocks of proteins. They consist of an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R group), all bonded to a central carbon atom. The side chain varies among different amino acids, giving each its unique …
