Like all other foods of plant or animal origin, milk contains several indigenous enzymes which are constituents of the milk as secreted. The principal constituents of milk (lactose, lipids and proteins) can be modified by exogenous enzymes, added to induce specific changes. Exogenous en- zymes may also be used to analyse for certain constituents in milk. In addition, milk and most dairy products

We shall study other examples of additions to the double bonds of alkenes. We begin with the additions of hydrogen halides, sulfuric acid, water (in the presence of an acid catalyst), and halogens

The important of acid-base reaction: 1. is a simple, fundamental reaction. 2. enable you to see the mechanism of the reaction 3. illustrate the process of bond breaking and bond making 4. examine important ideas about the relationship between the structure of molecules and their reactivity

Of the three groups of biopolymers, protein have the most diverse function. Most of its molecular weights are much larger. Their shaps cover a range from the globular protein to the helical coils of a α–keratin. But all proteins have common features. Proteins are polyamides and their monomeric units are about 20 different α-amino acids

4.7.I Occurrence and microheterogeneity B-Lactoglobulin is a major protein in bovine milk, representing about 50% of total whey protein and 12% of the total protein of milk. It was among the first proteins to be crystallized, and since crystallizability was long considered to be a good criterion of homogeneity, B-Ig, which is a typical

Teaching Objectives To get students know the value of helping others To understand the purpose of writing and organization of the text To reinforce some basic linguistic knowledge by doing various types of exercises

◼ What are the main challenges of translation and how do organisms overcome them? ◼ What is the organization of nucleotide sequence information in mRNA? ◼ What is the structure of tRNAs, and how do aminoacyl tRNA synthetases recognize and attach the correct amino acids to each tRNA? ◼ How does the ribosome orchestrate the translation process?
