Importance of stereoisomers in a biological system Isomers are compounds that have the same molecular formula but different structural formulas. Stereoisomers are isomers that have the same sequence of bonded atoms‚ but they differ in their three dimensional orientation in space. [pic] shown above is an example of the two types of Stereoisomers; Enantiomers‚ which are stereioisomers which are non-superimposible mirror images‚ much the same as one’s left and right hands are the same

One biological explanation for unipolar depression is the monoamine hypothesis. The monoamines are a group of neurotransmitters which include serotonin‚ noradrenaline and dopamine. You will recognise the latter‚ dopamine‚ from the biological offering of an explanation for schizophrenia. The monoamines are believed to regulate mood. One of the functions of serotonin is to regulate the other neurotransmitters. Without the regulation provided by serotonin‚ erratic brain functioning and thinking patterns

How do the four biological explanations fit together to explain schizophrenia or are they mutually exclusive? The biological explanation can be divided into subcategories to explain schizophrenia; genetic‚ biochemistry (dopamine hypothesis)‚ brain structure and season of birth explanation. Firstly there’s genetics. This view says some people posses certain genes that predispose them to schizophrenia. However‚ if schizophrenia was totally and always inherited then concordance rates between MZ

Biological and Humanistic Approaches to Personality PSY250 As research into personality progressed‚ scientists began to look beyond psychoanalysis and trait theories for other explanations into how personality develops. They started to look at the biological factors that influence personality formation (Hans Eysenck‚ Jeffrey Gray‚ Sir Francis Galton (genetic study of twins))‚ the effect of growth needs on personality formation (Abraham Maslow)‚ and the basic aspects of the humanistic personality

Discuss the disruption of biological rhythms 24m One example of disruption of biological rhythms is due to shift work and shift lag. This disrupts your sleeping pattern because it means you are required to be alert at night‚ so need to sleep during the day. This reverses and disrupts your circadian rhythm‚ becoming desynchronised where it is no longer entrained by EZ’s. There are many consequences of desynchronisation such as sleep deprivation. Shift workers find it hard to sleep during the day

What are the central assumptions of biological theories of crime? How do such theories differ from other perspectives that attempt to explain the same phenomena? Biological Theories of Crime These theories are provided by contemporary criminologist who relates the interaction between surrounding social and physical environments with biological influences and how it in turn shapes behavioral propensity and criminal activities too. Many researchers think that it can be passed down to their child to

the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids‚ and nucleic acids (Sheeler & Bianchi‚ 1980). Proteins are made up of polymers of amino acids. The shape
