Detailed explanation-1: -Proteins can be divided into two categories: fibrous, which tend to be insoluble in water, and globular, which are more soluble in water.

Detailed explanation-2: -Globular proteins are insoluble in water.

Detailed explanation-3: -Globular proteins are spherical in shape and usually water soluble. Examples of globular proteins include haemoglobin, insulin and many enzymes in the body.

Detailed explanation-4: -Two general kinds of proteins are found in cells, water soluble and water insoluble proteins. Water soluble proteins, which include enzymes and transport proteins, are found free in cellular compartments such as the cytoplasm, nucleus, or endoplasmic reticulum.

Detailed explanation-5: -Globular proteins are soluble in water. Globular proteins have four levels of structure: Primary-The amino acid sequence.
